MORE SINGERS... so chuuya is a few years younger and primarily runs a literature themed bar BUT he's had a side gig for a few years as a vocalist/lyricist! if you're down they could definitely have either worked together or just met through that at some point, maybe compared notes or something-- chuuya might have done some lyric writing for other bands at some point because his doesn't perform much and he just needs creative outlets sometimes tbh.

he's also had a string of relationships that didn't work out in the past so hey if you want more exes i'm down with that too!

+ he's a criminal & antagonist in his canon so that could potentially get interesting? he's about to get his regains wiped so he won't know about it again for a bit, whoops.
